CARBURETER.

SPECIFICATION forming part of Letters Patent No. 746,173, dated December,& 1903- Applioation filed January 2. 1903.

To all whom it may concern:

Be it known that 1, CHARLES E. SAYRE, a. citizen of the United States of America, and a resident of St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Garbureters,

of which the following is a specification.

My invention relates to improvements in carbureters, and has for its objectto automatically control the supply of hydrocarbon to the various compartments of the device.

With this and other hereinafter-specified objects in view my invention consists of a receptacle divided into compartments, a suitable supply connection with said compartments, a valve in said connection, passage-- ways between said compartments, and means governed by the quantity of hydrocarbon in said compartments for operating said valve.

My invention further consists of the fea tures of construction and combination of parts hereinafter more particularly described and claimed. v

In the accompanying drawings, forming part of this specification, Figure 1 is a transverse section of my improved carburetor, which is shown connected with a supply-tank. Fig. '2 is a plan view of Fig. 1, shown partly in section. Fig. 3 is a detail section of aportion of the carbureter, and Fig. 4 is aview of one of the frames for supporting the ends of the curtains in the carbureter.

l and diffuses the oil with air passing through the device is in operation.

In the drawings let A represent the carbureter, which is preferably inclosed by a cylindrical receptacle 2. This receptacle is divided into a plurality of superposed comdivided by curtains 7, 8, and 9 into a series of circular cells or. passage-ways 10, 11, and

12. These curtains are preferably constructed of absorbent material,- such as lamp-wick, which readily absorbs thehydrocarbon oil the compartments. The partition 7 hangs lower in each compartment than do the curtains S or 9, so as to prevent the carbureted air shortcircuiting between the cells when The curtain 7 starts at'the outer wall 2, nearly completes a Serial No. 137,487- (No model.)

' circle, and then swerves inward at 7 to an extent about equal to the space between the outer wall 2 and the curtain 7, the curtain then making'a series of similar circuits which graduallyrgrow smaller and open into the central chamber 15. The curtains 8 and 9 divide the passage-way thus formed into cells which traverse its length and also open into the central chamber 15.

Each compartment 3, 4, 5, and 6 is divided from the next superposed compartment by means of floors 16, 16, and l6 A series of curtains hang in each compartment and form a series of cells similar in construction to as shown in Fig. 4, may beused at the ends of the passage-ways of the compartments for holding the curtains in position. Compartment 3 is connected with compartment'4 by means of the overflow passage-way B." This passage-way is a tube 17, which is attached at 18 to the floor 16 of compartment 3 and projects above the surface of the hydrocarbon oil 'in said compartment. A branch tube 19 depends from the tube 17 into the oil and has connection with the main tube at 20, sothat the heavy oil overflows from near the bottom of compartment 3 into compartment 4. The in her surface, 21- of each compartment is covered with absorbent material 22 such as used forthecurtains. The curtains are suitably attached to the covering 22, as by sewing.

-Said covering may be cemented or riveted to the inner surfaces of the receptacle. 'The floors of the respective compartments are strengthened by means of the posts 30. Compartment 4 has communication with compartment 5 by means of the overflow passage-way 23 and compartment 5 'withcompartnientt by means of the overflow passage-way 24. The overflow passage-ways are all similar in construction. The overflowpassage-way 23,

is positioned near the outer wall 2 in compartnient 4 and has communication through the opening 27 with compartment 5. The overflow passage-way 24 is. positioned near the center of compartment 5 and has communication through the opening 28 with compartment 6. A compressed-air-supply tube compartment 6, and an outlet-tube 32 for the carbureted air is connected with compartthose in compartment 3. A wire frame 49,

Ioo.

'31 connects with the cells 10, 11, and 12 in ment 3, as shown in Fig. 1. Air entering through the inlet 31 circulates through the cells in the lower compartment and passes up through the tube 24 into compartment 5. After circulating through the cells of compartment 5 it passes through the tube 23 into compartment 4. After circulating through the cells in compartment 4 it passes through the tube 17 into compartment 3,and after circulating through the cells of compartment 3 passes out ofthecarbureterthrough the tube 32,which may lead to the mixing-chamber (not shown) of any suitable burner. A pipe 33 connects the top of the receptacle with the top of any suitable hydrocarbon-supply tank 34 to maintain an equilibrium of pressure in the tank and in the carhureter, as above described. A tube 35 from said supply-tank discharges into a trough 36, which delivers hydrocarbon from said tank into compartment 3 through the perforation 36 in the wall 2 of the carbureter. Any suitable valve 37 is attached over the outlet of the pipe 35 and has its stem 38 connected with the controllingrod 39. This rod has its lower end secured to a float 40, arranged within the chamber 41. The chamber 41 is attached on the side 2 of the receptacle A and communicates at 42,as shown in Fig. 1, with the compartment 6 of the carbureter.

In supplying hydrocarbon oil to the car bureter the tank 34 is filled, and the float 40 being in its lower position retains the valve 37 open. The hydrocarbon oil in the supplytank 34 flows through the pipe 35 down trough 36 into compartment 3. The oil overflows through the siphon 19 into compartment 4 and on through the succeeding compartments and siphons until it reaches the desired level in chamber 41 and closes the valve 37 by lifting the float 40. The action of supplying hydrocarbon oil to the carhureter is thus antomatic. It will be noted that the overflowtubes 19 in the various compartments conduct the heavier oil into the compartment next beneath the one from which the oil is being discharged, and hence eventually all of the heavy matter within the oil is deposited in the lowermost compartment. A suitable tube 48 is connected with compartment 6 for drawing off the refuse and heavier substances which are not vaporized.

In operation air is introduced through pipe 31, whence it passes through the various cells in the carhureter, as above described, and out through the tube 32. Air passing through the carbureter is thus exposed to a maximum surface of oil in the receptacle, thereby charging the air with the hydrocarbon vapors, so that the same will support combustion. The compartment 41 is provided with a plug 43, which is threaded at 44 into the shell 2. By removing this plug the valve mechanism is readily accessible for cleaning or repairing.

Although I have specifically set forth the particulars of one embodiment of the present invention, yet it will be obvious to those skilled in the art to which this invention relates that many changes may be made within the spirit thereof-such, for instance, as the provision of rectilinear or spiral passageways instead of those described, the main object of the construction set forth being the arrangement of a passage-way divided into a series of cells which starts at or near the outer surface of the containing-wall and turns within the same until it eventually ends near the center of the structure. It will be observed that such arrangement may be used in connection with a containing-receptacle square or otherwise shaped in cross-section.
